OBI SystemVerilog synthesizable interconnect IPs for on-chip communication
Loading README and project media…
The repository contains a collection of SystemVerilog IPs for the OBI v1.6 standard.
They are designed by PULP-platform and are available under the Solderpad v0.51 license (See LICENSE).
As the OBI protocol is very configurable, the IPs are designed to incorporate specific parameters for the design:
ObiCfg: This specifies the configuration used for the OBI protocol being input or output from the link. A default config can be found in the obi_pkg.sv. This config should be aligned with the req and rsp structs.obi_req_t: The OBI request struct is designed to be generated with a macro available in the include/obi/typedef.svh include file and has fields for the handshake and a field for the A channel.obi_rsp_t: The OBI response struct is designed to be generated with a macro available in the include/obi/typedef.svh include file and has fields for the handshake and a filed for the R channel.Most IPs will also support a SystemVerilog interface variant, also based on ObiCfg.
obi_mux.sv: A multiplexer IP for the OBI protocol.obi_demux.sv: A demultiplexer IP for the OBI protocol.obi_xbar.sv: A crossbar interconnect IP for the OBI protocol.Solderpad Hardware License, Version 0.51
